Boccaletti develops and exploits high-contrast coronagraphic imaging instrumentation for direct detection and characterization of exoplanets and circumstellar debris disks, including the four-quadrant phase-mask coronagraph built at Observatoire de Paris-PSL now flying on JWST's MIRI instrument, which recently resolved the inner dust belt and all four planets of the HR 8799 system in the mid-infrared.

Wang's BOBA group directly images young, self-luminous exoplanets by suppressing host-star glare with coronagraphy, extreme adaptive optics, and long-baseline optical interferometry (e.g. Keck/KPIC, VLTI), combined with physics-based computational signal-processing and machine-learning algorithms to extract faint planetary signals. He led early JWST direct-imaging detections of exoplanets and studies their orbits, formation, and atmospheres via high- and low-resolution spectroscopy. This is offered as an astronomy pivot on the filter: the enabling technology is increasingly complex opto-mechanical and computational instrumentation pushing spatial and spectral resolution, rather than a quantum sensor per se.
